This document is not restricted to specific software and hardware
versions.

The information in this document was created from the devices in a
specific lab environment. All of the devices used in this document started with
a cleared (default) configuration. If your network is live, make sure that you
understand the potential impact of any command.

If you enter http://www.domain.com/Test.html, an error is returned. The
error states that the document cannot be found. The error occurs because you
entered an uppercase T, rather than a lowercase
t. The CSM sends a reset (RST) immediately after the CSM
receives the client GET request, which results in the error.

For case insensitivity, configure the CSM to allow any possible
combination of uppercase and lowercase characters. Here is an example:

Test
TeSt
TEST

Now, consider this policy map, which references another user-defined
url-map with the name ANY_CASE. This policy map uses regular
expressions to allow for case insensitivity:

The latter of these two configurations defines the regular expression.
The regular expression allows for any combination of uppercase and lowercase
characters for the word "test", which can be followed by any other sequence of
characters. The addition of the wildcard (*)
denotes any other sequence of characters to follow.
